MACHINE FOR PERi-ORATING PAPER.

SPECIFICATION forming part of Letters Patent No. 593,694, dated November16, 1897.

Application filed January 23, 1896- Serial No. 576,534. (No model.)

To all. whom it mayconcern:

Be it known that we, HAROLD W; SHON- NARI) and GEORGE HOWLETT DAVIS, ofNew York, in the county and State of New York,

have invented a certain new'and useful Improvement in Machines forPerfo'ratingPa per, of which the following is a specification.

The object of our improvement is to produce a simple, cheap, andefficient machine for perforating 'paper,'and particularly forperforating such paper as is used to control automatio or mechanicalmusical instruments.

Our improvement is embodied in a machine in which a perforated musicsheet is fed through as a pattern and an unperforated sheet is fedthrough correspondingly, the perforated music-sheet serving as 'apattern and controlling devices which perforate the unperforated sheetsimilarly.

We will describe in detail a machine embodying our improvemenuand thenpoint out thenovel features'in the'claims.

In the accompanying drawings, Figure l is a side elevation of a machineembodying our improvement. Fig. 2 is a central longitudinal section ofthe same. Fig. 3 is a plan or top view with certain parts broken awayand others shown in horizontal section. Fig. 4 is a transversesectiontaken for one lateral part in one vertical plane'and forthe otherlateral part in another Verticalplane. 7 L

Similar letters and numerals of reference designate corresponding'partsin all the figures. I

'A designates the frame of the machine. It may be made of ,wood or anyother suitable material and will consist of side frames united bycross-pieces or stretchers. As here shown its side pieces comprise lowerrails a and upper rails a In the lower rails are bearings a for thejournals of' rolls B B to which a sheet of paper B is attached. When putinto roller B it passes over punch-blocks O and beneath punches 0 ThereWill be as many of these punch-blocks and punches as there are rows ofperforations to be formed in the.

paper B. All the punoh-blocks may be fastened to one support 0, made inthe form of a bar with appropriate openings through it, and the puncheswill preferably all be supported in common bars 0 0 The bars 0 csupporting the punches, are immovable; but

the punches may have an independent longireciprocated transversely tosaid bars along suitable guides F by means of levers F fulcrumed upon arod f. These levers, as here shown, are made in the form of elbow-leversand are represented as having their long arms made in two pieces rivetedtogether; but this latter feature of construction is immaterial. Theupper ends of these levers project through a rest G, supported by therails a of the frame A. Springs f tend to raise these ends, and aperforated sheet H depresses them or allows them to rise, accordingly asperforate or imperforate portions pass. over them. The sheet Hwhenoriginally introduced is wound upon a roller H, which is journaled inthe'rails a of the frame A, and is passed onward to a roll H by which itis taken up. This roll H may be moved by hand or otherwise. Above therest G is a bar I, shown as connected at one end by a hinge z to one ofthe rails a of the frame A, and securedat the other end, which rests ina U -shaped bracket, by means of a catch 1'. The said catch t is pivotedat 4 to a bracket 1, having a U -shaped bearing 2, and comprises a toeportion 5, which rests upon the end of the bar I to retain it inposition, and a handle portion'3, by means of which it may be operated.This catch is further provided with a curved elongated slot 6, throughwhich passes a bolt, upon the end of which is fitted a thumb-nut '7. By

this arrangement the toe portion 5 of the catch can be adjusted so as tofit tightly upon the end of the bar I to hold it to its seat, and may beretained in this position by means of the thumb-nut 7, which is screwedup tightly against the said catch. The bar I may advantageously be madeof concavo-convex form in transverse section, as represented in Fig. 2,to allow the adjacent ends of the levers F to rise into it. The sheetpasses between the feed-rollers J J 2 and is drawn onward by them at aproper speed.

Each of the bars F has a notch on the under side, and the notches of allthe bars will be above the punches C while imperforate portions of thesheet II are passing over the upper ends of the levers F Then thepunches can rise each time the punch-blocks are raised by the toes ofthe cams E, and hence will not cut the paper. To avoid anymisunderstanding, we will add that this upper movement of the puncheswill be produced by the unperforated sheet or strip B while restingabove the punch-blocks.

W'henever any one of the levers F is permitted to rise through aperforation of the sheet H, the corresponding bar F will bereciprocated, so that its notch will be moved beyond the correspondingpunch, and the latter then will be made immovable relatively to the bars0 0 so that on the next upward movement of the punch-blocks such punchso held immovable will cut the sheet B. Thus the sheet B will beperforated to correspond with the sheet II.

The sheet B is moved along by means of feed-rollers K K between which itpasses. Motion is correspondingly imparted to the feed-rollers J J 2 K Kby means of ratchetwheels j on the rollers J K, pawlsj 70 coacting withsaid ratehet wheels and a lever L, which operates said pawls. This leverL is pivoted at one end, as shown, to the block D, and is fulerumedintermediate its ends in a slotted bracket by means of a slot in thelever engaging a pin Z, the slot in the said lever permitting the latterto slide longitudinally upon the pin as it oscillates. The rollers J Kare each provided with a cam IV and lever X, by which to enable saidrollers to be made to bear with greater or less pressure upon thesheets.

Although we refer to the term paper, we wish to cover the machine forperforating any analogous material. Although we have referred to theparts F as levers, it will be seen that they may be regarded as fingers,and that although we have spoken of the parts 1* as bars they may beregarded as stops for the punches.

In Fig. 1 we have shown the levers F as connected by means of rods Swith levers S, constituting armatures for electromagnets S There will bea number of these levers and armatures corresponding to the number ofthe levers F The magnets may be mounted upon an L-shaped rail 5,suitably supported by uprights extending from the frame A. Thearmature-levers may be fulcrumed to this rail. The electromagnets are incircuit with a battery or other source of electricity S having a numberof branches extending to the different magnets and provided withcontacts 3 5 These contacts are normally separated. Above them mayextend the manual-keys of an ordinary piano or organ, so that on thedepression of the keys the branch circuits for different magnets will beclosed, and this will cause the energizing of such magnets and themoving of the corresponding levers F Instead of operating the contacts 5s by means of keys K they may be operated by means of a perforated sheetor analogous device of any kind. YVe intend to provide a machine withthis electromagnetic mechanism, as well as the mechanism which isoperated by the sheet II. The electromagnetic mechanism will be thebetter where a music-sheet of thin paper is to be used for thereproduction of others, whereas the mechanism controlled by the sheet IIis suitable for music-sheets II of thick strong paper.

\Vhat we claim as our invention, and desire to secure by Letters Patent,is

1. In a perforating-machine, the combination of means for feeding animperforated sheet, punch blocks arranged below the sheet and mounted toreciprocate in guides upon either side of the machine-frame, a retaryshaft journaled in bearings below the punch-blocks, cams on said shaftadapted to act upon the under side of the punch-block mountings toreciprocate the same, a stationary support above the punch-blocks, aseries of punches loosely mounted in said support, a series oflocking-bars arranged to move freely back and forth in guides above saidsupport, a plurality of elbow levers tulcrumed upon a common rod andeach having its lower end connected to one of the lockingbars and itsupper portion bent forward horizontally and terminating in avertically-projecting arm or point, a table or rest G, up through whichthe points of the levers project, an arched bar I, arranged above therest and hinged at one end to the machine-frame, and a perforated sheetarranged to travel between the said arehed bar and rest, as and for thepurpose described.
